This is an offshoot of the National Reciprocity thread...the states whose IDs don't pass muster are going to put fathers who owe child support in a bind. If someone owes pastdue child support, they can be denied a passport. So, there are residents of several states who will basically be prohibited from flying, even domestically. In my case, I have paid over $250K in child support, and was $3000 in arrears...it just accumulated over 15 years. At any rate, I was denied a passport until I had a ZERO balance, and it still took 90 days to get clearance. In my case, I wanted to go to Cancun, so it was strictly a leisure trip, but what if someone lived in one of the noncompliant states and needed to travel domestically for work??? They had best get paid-up, in a hurry. In a perfect world nobody would ever be pastdue, but it happens and it seems draconian to make those folks unable to board a commercial plane.
